As Lisa Kudrow as Wanda Pierce in Bojack Horseman once said, "When you look at someone through rose-colored glasses, all the red flags just look like flags," which is one of the most poignantly true statements anyone has ever made, especially in an adult cartoon. When you love someone, or when you want to love someone, it's easy to overlook their flaws. Only when you have a healthy distance from a situation can you see it for what it is.
But some red flags are redder than other red flags. Some flags are so red that you should actually call them crimson. These behaviors, which range from subtle to flagrant, help reveal people's true colors, whether they like it or not. Reading through these might make you thankful that the people in your life aren't the monsters seen here. Or maybe they are and you're figuring it out. Either way, it's good to know.
